Re: Ball Flight Model

So as promised, I have included some additional data sets to test for your model.

I have yet to confirm the results to actual measured results from the balls flight trajectories.

Once again my model only includes air resistance no magnus force. All Paramters needed should be included on the plots.

The ball in the plot is to scale.

The only trouble I am having is determining the required force based on the lauch velocity. The numbers are way to small in my opinion. Maybe it is because using Vf = Vi + at assumes accel is constant over time and because I assume the force is applied over t=0.5 seconds which may be too long.

I don't know, I haven't spent time looking into it. But I would expect the required force to be in the 100lbf+ range for quick shots. Any thoughts?

Hope this helps,
Kevin
